In a collision determination device for determining a type of front collision of a vehicle, a collision determination unit is configured to determine that the collision type is full overlap front collision as collision of the vehicle with an obstacle across substantially the entire width of a front surface of a vehicle body in a case where initial values as values at an early phase of the collision for a first lateral acceleration and a second lateral acceleration are both less than a full overlap determination threshold as a negative value.

A control device for controlling a passenger protection device for a vehicle includes an input unit configured to receive a first acceleration signal in a first axial direction and a second acceleration signal in a second axial direction which are generated by an acceleration sensor disposed in a side door of a vehicle, a determination unit configured to determine whether a collision has occurred in the side door of the vehicle using at least one of the first acceleration signal and the second acceleration signal, and a control unit configured to control a passenger protection device disposed adjacent to the side door of the vehicle based on a result of determining whether the collision has occurred.

A bumper reinforcement includes a body portion joined to a vehicle body front end portion through portions of the body portion on a first direction side and a second direction side in the vehicle width direction, and a reinforcing member joined to the body portion along the body portion. The body portion includes a first standard rigidity region, a high rigidity region, and a second standard rigidity region arrayed next to each other in this order in the vehicle width direction. The high rigidity region has rigidity higher than rigidity of the first standard rigidity region and rigidity of the second standard rigidity region and is positioned in a center of the body portion in the vehicle width direction. The reinforcing member is provided so as to at least partially overlap the high rigidity region and the first standard rigidity region through a first boundary position.

A method and apparatus of predicting a crash are provided. The method includes detecting coordinates of a target obstacle based on first coordinate information of a radar sensor and second coordinate information of an ultrasonic sensor, translating the second coordinate information to the coordinate system of the first coordinate information and generating translated coordinate information, estimating a position, speed, and acceleration of a vehicle if the vehicle is a predetermined distance from the target obstacle based on the translated coordinate information, determining a potential crash type between the vehicle and the target obstacle based on the estimated position, speed and acceleration of the vehicle, determining a three-dimensional movement trajectory based on the estimated position, speed and acceleration of the vehicle and the determined crash type, and predicting a crash point of the vehicle, a crash point of the target object and a crash time based on the three-dimensional movement trajectory.

Devices and methods for absorbing crash energy are described. A uniform deceleration unit (UDU) includes a first layer having a top and a bottom, the top of the first layer arranged to be outwardly facing towards a direction of a crash force when the UDU is installed, a second layer on the bottom of the first layer, the second layer having a rib and web structure with a first arrangement, a third layer on a bottom of the second layer, the third layer having a rib and web structure with a second arrangement, and a fourth layer on a bottom of the third layer, the fourth layer arranged to be inwardly facing when the UDU is installed, the fourth layer including a reaction beam arranged to allow the first, second, and third layers to crush. The UDU may be installed in or positioned near the side sill beam.

Apparatus, systems, and methods generally including detecting, using a sensor, an impact at a vehicle; before, during, or after detecting the impact, storing a first data set associated with the vehicle in a first memory; in response to detecting the impact, retrieving the first data set from the first memory; transmitting, using a first short range communication device, the first data set via a first wireless signal; receiving, using a second short range communication device, the first data set via the first wireless signal; and storing the first data set in a second memory; and after storing the first data set in the second memory, retrieving the first data set from the second memory; wherein the first short range communication device is part of the vehicle; and wherein the second short range communication device is part of an infrastructure.
